1, infection (rare) causes: insufficient preoperative prophylactic medication, intraoperative aseptic operation is not strict, and irregularities during postoperative monitoring may cause. Active anti-inflammatory treatment;
2, elevated intraocular pressure causes: viscoelastic residue in the anterior chamber (the most common), compression of the lateral incision or the main incision will help; the ICL is too large, take out and replace the smaller size of the lens;
3, the arch is too small causes: the ICL is too small, and the arch is too small to be dealt with for one week after surgery. If the patient's best-corrected visual acuity is found to be decreasing, then the larger model of lens should be removed and replaced;
4. Reason for too large an arch: the implanted lens is larger than the anatomical needs of the operated eye. In the early stage, the crystal is retained and pupil dilation is given in order to identify whether the cause of high intraocular pressure is due to the residual viscoelastic agent or truly due to the ICL being too large; asymptomatic patients with high arches do not need to be handled, and standard followup is performed, and for patients with arches larger than 1000 micrometers, close follow-up is performed in the early stage, and then back to the standard followup mode; if there is an increase in intraocular pressure, accompanied by anterior displacement of the iris and shallowing of the angle of the aperture, a larger model of lens is taken out and replaced. smaller size lens;
5. Traumatic cataract causes: injury during surgery. Puncture of the anterior capsule is very rare, once it occurs, it should be immediately changed to lens removal and IOL implantation; when compression of the ICL footplate toward the back, it may contact the anterior capsule to produce turbidity, this small turbid zone is located in the periphery, it will not have an impact on the vision, and it does not need to be dealt with;
6, cataract causes: late postoperative complication, the arch height of the surgery is too small may occur in the anterior capsule under the cloudiness of the lens. An arch height less than or equal to 1/4 of the corneal thickness (<150 micrometers) should be closely monitored. If no clouding of the lens or loss of vision occurs, ICL replacement is not necessary; if clouding of the lens or progressive loss of vision occurs, replacement with a larger type of lens is necessary.
